“…Zinc oxide (ZnO) is a promising n-type semiconductor material that is used in a wide range of applications, such as gas detection [1,2,3,4], dye-sensitized solar cells [5,6,7], antibacterial surface coatings [8], light-emitting diodes (LEDs) [9,10], nanopower generators [11], ultraviolet (UV) detection [12,13,14,15], and photocatalytic applications [16,17,18]. ZnO nanostructures have a direct wide band gap (3.37 eV) [19], chemical stability [20], optical [21], piezoelectric [22,23,24], and electrical [25] properties.…”

Zinc oxide/reduced graphene oxide nanocomposites (ZnO/rGO) are synthesized via a simple one-pot solvothermal technique. The nanoparticle–nanorod turnability was achieved with the increase in GO additive, which was necessary to control the defect formation. The optimal defect in ZnO/rGO not only increased ZnO/rGO surface and carrier concentration, but also provided the alternative carrier pathway assisted with rGO sheet for electron–hole separation and prolonging carrier recombination. These properties are ideal for photodetection and photocatalytic applications. For photosensing properties, ZnO/rGO shows the improvement of photosensitivity compared with pristine ZnO from 1.51 (ZnO) to 3.94 (ZnO/rGO (20%)). Additionally, applying bending strain on ZnO/rGO enhances its photosensitivity even further, as high as 124% at r = 12.5 mm, due to improved surface area and induced negative piezoelectric charge from piezoelectric effect. Moreover, the photocatalytic activity with methylene blue (MB) was studied. It was observed that the rate of MB degradation was higher in presence of ZnO/rGO than pristine ZnO. Therefore, ZnO/rGO became a promising materials for different applications.

“…Optical spectroscopy studies indicate that the PL emission properties can be adjusted by the dopant concentrations in the yttrium oxide NPs, which in turn can be controlled by the plasma process conditions. Other MONS including ZnO nanosheets, TiO 2 nanotube, europium‐doped ceria NPs CeO 2 , CuO NPs, CuO/TiO 2 nanocomposite, Ag/TiO 2 nanocomposite, SnO/GNS nanocomposite were recently synthesized using the microplasma‐assisted liquid‐phase method. These results confirm high potential of microplasmas in oxide materials processing and deposition for optoelectronics, sensing, and energy applications.…”

“…The NP shape can be transformed from spherical particles at short reaction times (10 min), to rods at middle reaction times (15 min), to sheets at long reaction times (70 min), and even to cubes at very long reaction times (240 min) . The shapes of ZnO NSs have been controlled by varying the capping agents during the microplasma‐assisted liquid‐phase synthesis . It is interesting to observe that nanosheets, nanodrums, and nanoneedles of ZnO NSs can be produced by using sodium dodecyl sulfate, fructose, and cetrimonium bromide, respectively, during the microplasma‐assisted synthesis at room temperature, similar to wet chemical approaches.…”

“…As it was demonstrated with other materials investigated for their antibacterial properties, the surface structure of diamond films is a strategy to implement a mechanical antibacterial mechanism of action against certain strains of bacteria [211][212][213][214][215]. The motile bacteria, able to move by themselves in their environment such as E. coli are especially sensitive to sharp points able to puncture their membranes.…”

antibiotic resistance in bacteria is a current threat causing an increasing number of infections of difficult clinical management. While the overuse and misuse of antibiotics are investigated to reduce them, the need for alternatives to approaches is rising. carbon-based materials shown recent moderate to high antibacterial properties and diamond, thanks to its superior mechanical, tribological, electrical, chemical and biological quality is a choice material to investigate for safe antibacterial films, coatings and particles. here, the antibacterial properties of diamond films, nanodiamonds, Dlc films and a comprehensive list of the composites developed from them are discussed along with a summary of the bacterial strains used and the most efficient composition and/or concentration discovered. in a later stage, the mechanisms of action and the parameters that are believed to influence them are discussed and finally, an overview of the biomedical and food industry applications is given.
